GAGE-RUNNER ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 496,566, dated May 2,1893.

Application filed December 10,1892. Serial No. 454.776. (No model.)

To @ZZ whom it may concern:

Beit known that I, DELZON G. HOBBY, a

A citizen of the United States, residing at Albion, in the county ofOrleans and State of New York, have invented a new and usefulGage-RunnerAttachment for Walkin g-Plows, of which the following is aspecification.

This invention relates to plow attachments; and it has for its object toprovide an improved gage runner attachment for walking plows which shallprovide means for conveniently raising and lowering the wheel of theattachment, so that the depth at which the plow is to be run can beeasily governed by the operator without stopping the plow.

To this end the invention primarily contemplates certain improvements inattachments of this character.

With these and other objects in view which will readily appear as thenature of the in- `vention is better understood, the same consists inthe novel construction, combination and arrangement of parts,hereinafter more fully described, illustrated and claimed.

In the accompanying drawings:-Figure l is a side elevation of a plowhaving a gage runner attachment as contemplated by the presentinvention. Fig. 2'is a horizontal sectional view through the attachmenton the beam. Fig. 3 is an enlarged detail in perspective of theattachment detached from the plow.

Referring to the accompanying drawings, A represents an ordinary plowbeam carrying the usual plow B, and having at the rear thereof theordinary handles O. The plow beam A, is provided in one side thereofnear the clevis end with the side notch or recess D, over which isclamped the attachment plate E. The attachment plate E, is provided onthe inner side thereof with the offstanding securing rib F, which snuglyfits in the side notch or recess in the beam to hold the plate steady,and said plate i's secured to the beam on the single bolt G. The saidattachment plate E, is provided upon the outer face thereof with theopposite inturned grooved guide tongues H, and is extended integrally lat one end as at I, and carries on such end below its center the pivotpin or stud bolt J the function of which will be shown.

The inturned grooved guide tongues H, of the attachment plate, overlapthe side edges of the vertically adjustable sliding wheel standard K.The sliding wheel standard K, which is guided in its vertical adjustmentin the grooves of the guide tongues, is provided with a centrallongitudinally disposed strengthening rib 7e, and carries upon theextreme lower end thereof the gage wheel L, which is adapted to travelover the ground to gage the depth at which the plow is to run. Anoperating bellcrank lever M, is pivoted at its angle on the pivot boltJ, of said attachment plate and is provided at the extremity of one armthereof with the slot mf, which loosely engages the pin N, projectingfrom about the center of the sliding wheel standard. The said bell cranklever M, is provided with an angle brace fn, connecting the two armsthereof and has connected to the extremity of the free' arm thereof theoperating rod O, which is connected to one end of the controlling leverP. The lever P, is pivoted to one of the plow handles and carries aspring actuated pawl p adapted to engage the notched segment Q, securedto the plow handle alongsideof the lever P. By manipulating the lever P,the wheel standard can be raised and lowered at the option of theoperator to control the depth of the plow.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

In an attachment for plows, the combination with the plow beam having aside notch or recess at one end; of an attachment plate having at onesido an off-standing securing rib F, adapted to snugly iit in the sidenotch or recess in the beam, opposite inturned' grooved guide tongues,and an integral end extension I, havinga pivot pin or stud bolt, at

single bolt passing through the attachment plate and said beam lto holdthe former in position, a vertically adjustable wheel standard adaptedto slide on the attachment plate between the grooved guide tonguesthereof, said wheel standard carrying a gage wheel or run- 11er at itsloWer end and provided with an in- In testimony that I claim theforegoing as termediate outwardly projecting pin, abraeed my own I havehereto affixed my signature in 1o bell crank lever pivoted at its angleon said the presence of two Witnesses.
